Analysis of the acceleration of the multi-level vibration of the tank as firing

Abstract

Aiming at the system level vibration problem caused by the strong impact load during the tank firing, the tank is divided into several levels according to the vibration transmission path, such as barrel, cradle, turret, seat ring, car body and wheel. The multi-level vibration response characteristics of the tank during firing are obtained by arranging acceleration sensors at the typical positions of each level. Based on the time domain analysis method, the vibration acceleration at the positions of cradle, turret, seat ring, car body and wheel is analyzed, and the pulse amplitude and pulse time of vibration acceleration at each level are obtained. The analysis shows that under the action of firing load, the acceleration amplitude of muzzle, cradle, turret, seat ring, vehicle body and wheel decreases in turn. And the peak acceleration at the muzzle position is the largest, about 1400g, and the peak acceleration at the wheel position is the smallest, about 0.6g. The results will provide support for obtaining the multi-level vibration characteristics of the tank under the fire load and revealing the vibration transmission law of the tank under the fire load.
